A/D Input Port Scan-Select Register ADPSS
The Special Function Register ADPSS contains control bits to select
the analog input channel(s) to be scanned for A/D conversion. The
reset value of ADPSS is (00000000). Its hardware address is E7H.
ADPSS is not bit addressable.
If all bits are ‘0’ then no A/D conversion can be started. If ADPSS is
written while an A/D conversion is in progress (ADSST in the
ADCON register is ‘1’) then the autoscan loop with the previous
selected analog inputs is completed first. The next autoscan loop is
performed with the new selected analog inputs.

A/D Result Registers ADRSLn and ADRSH:
The binary result code of A/D conversions is accessed by these
Special Function Registers. The result SFR are read only registers.
The read value after reset is indeterminate. Their data are not
affected by chip reset. They are not bit addressable.
There are 8 Special Function Registers ADRSLn
(ADRSL0...ADRSL7) – A/D Result Low byte – and one general SFR
ADRSH – A/D Result High byte – . Each of ADRSLn is associated
with the coincidently indexed analog input channel ADCn
(ADC0/P5.0...ADC7/P5.7). Reading an ADRSLn register by
software copies at the same time the two highest bits of the 10-bit
conversion result into two latches, thus preserving them until the
next read of any ADRSLn register. These two latches form bit
positions 0 and 1 of SFR ADRSH, the upper 6 bits of ADRSH are
always read as ’0’.
Thus it is ensured to get the 10-bit result of the same single A/D
conversion by reading any register ADRSLn first and after it the
register ADRSH.
